Just to chime in, I've had the Omnilogic now since late fall of 2014. This is my first pool so I can't make comparisons, but I'd say it's fine as a pool panel, but I always have had some connectivity issues, and recently made those disappear for the most part by moving my wireless bridge in my pool shed to a better location.
What I DO like is that I can always control the pool while I am outside with my phone, which is always with me. Don't have to go hunting down a remote, or go to the panel itself. If you are having an issue with something, however, the phone or ipad versions don't really tell you anything. In fact, if you are having connectivity issues, the apps tend to just display the last known settings. I lost my signal the other day and the filter pump showed turned on to 70% no matter what I did, and changing the settings on the actual panel made no difference.
To me, the problem is that the app and the panel don't continuously talk back and forth. It takes several seconds and sometimes minutes for the panel to communicate changes to the device. So, if you make changes to the pool operation from a distance, with the delay, you might not actually get the response you are hoping for.
I was in Mexico recently and in the process of Slamming my pool back in Texas. I had forgot to set the pump to run all night, and since it normally doesn't run from about midnight to morning, I decided to turn the pump on. As an experiment, I made the pump changes with my iphone, and watched on my Ipad to see if those changes actually happened.
I just ordered the HL-CHEM system, which I will be adding to my system to automate the addition of liquid Chlorine (using a Rolachem 12 GPD pump) and Haywards AC003 (carbon dioxide solenoid and regulator with an injector). According to the folks at Hayward, this should work well through the Omnilogic, and when I'm logged into the actual Omnilogic signin page, rather than just the app, I will be able to see the status of the pool's ORP and PH, and know when it is dispensing chemicals.
Back to my opinion about the Omnilogic, I'd say it is a mixed opinion because I think it could be better, but I'm not sure that means there is something better out there on the market.
Cheers,
